Abstract
A method is for a circuit for a motor comprising first and second phase windings. The method comprises receiving alternating current (AC) power from the first and second phase windings at a direct current (DC) power supply and converting the AC power to DC power and receiving AC power from the first and second phase windings by at least one power switch between the first and second phase windings and switching the AC power by the at least one power switch. The method includes preventing the DC power supply from collapsing, by a first component connected to the DC power supply, when the at least one power switch is on during a first portion of an AC cycle and preventing the DC power supply from collapsing, by a second component connected to the DC power supply, when the at least one power switch is on during a second portion of the AC cycle.
